Description

Technical Field

[0001] This invention relates to the field of adhesive application for workpieces, and particularly to an adhesive application device for workpieces. Background Technology

[0002] During the production process, some workpieces require adhesive films to be pasted onto the areas to be glued, leading to the development of various adhesive application devices. Traditional adhesive application devices are typically press-type devices, which include a fixture for fixing the workpiece and a film pressing module positioned above the fixture. The film pressing module has an adhesive film positioned corresponding to the area to be glued on the workpiece. During press-type adhesive application, the workpiece is first fixed to the fixture, and then the film pressing module is pressed down onto the fixture to press the film onto the area to be glued. These press-type adhesive application devices are prone to generating air bubbles, affecting adhesive application performance and causing the film to easily detach from the workpiece. Furthermore, each application requires precise positioning of the film and the area to be glued, resulting in low accuracy in placement, reduced defect rate, and low application efficiency. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a workpiece adhesive application device that can reduce air bubbles, improve the accuracy of adhesive application position, and improve adhesive application efficiency.

[0004] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide a workpiece adhesive application device, including a fixing fixture for fixing the workpiece and an adhesive application module for pasting adhesive film onto the adhesive area of ​​the workpiece; the adhesive application module includes an adhesive feeding mechanism for feeding the adhesive film to the adhesive area and a rolling mechanism for rolling the adhesive film onto the adhesive area.

[0005] Furthermore, the adhesive application module also includes a moving mechanism connected to the rolling mechanism. The moving mechanism is used to drive the rolling mechanism to move towards the tail end when the rolling mechanism presses the adhesive sheet at the first end of the area to be adhesiveped, so that the rolling mechanism rolls the adhesive sheet onto the area to be adhesiveped from the first end to the tail end.

[0006] Furthermore, the moving mechanism is also connected to the glue feeding mechanism, and the moving mechanism is also used to drive the glue feeding mechanism to move towards the tail end of the area to be glued so that the film is peeled off from the glue feeding mechanism.

[0007] Furthermore, the moving mechanism includes a moving base, and the rolling mechanism and the glue feeding mechanism are distributed on a surface of the moving base facing the workpiece along the direction from the first end to the last end.

[0008] Furthermore, the glue feeding mechanism includes a peeling plate disposed on the movable base and a glue feeding assembly for moving the film through the peeling plate to the first end position of the area to be glued; the glue feeding assembly stops feeding glue after feeding the film to the first end position, and the rolling mechanism is used to move downward to press the film at the first end position when the glue feeding assembly stops feeding glue; the moving mechanism is used to drive the glue feeding mechanism and the rolling mechanism to move towards the tail end direction when the rolling mechanism presses the film at the first end position, so that the film can be peeled off from the peeling plate when the rolling mechanism rolls the film towards the tail end direction.

[0009] Furthermore, the end of the peeling plate near the glue feeding assembly is defined as the input end, and the end of the peeling plate near the rolling mechanism is defined as the output end; the glue feeding mechanism also includes a detection unit disposed on the movable base for detecting whether the first end of the film has been fed to the first end position outside the output end, the detection unit being electrically connected to a control unit; the control unit is used to control the glue feeding assembly to stop feeding glue according to the film arrival signal detected by the detection unit.

[0010] Furthermore, the peeling plate is defined as an inclined peeling plate, the input end is defined as an upper inclined input end of the inclined peeling plate, the output end is defined as a lower inclined output end of the inclined peeling plate, and the thickness of the lower inclined output end gradually decreases in the direction away from the upper inclined input end.

[0011] Furthermore, the film includes a film body and a detection portion disposed on the film body at one end away from the rolling mechanism; the detection unit is positioned such that when the first end of the film reaches the first end position, the detection unit can detect the detection portion.

[0012] Furthermore, the glue feeding assembly includes a glue feeder for carrying the adhesive tape, a plurality of glue feeding rollers disposed between the glue feeder and the glue peeling plate, and a drive unit for driving the glue feeding rollers; the adhesive tape carries the adhesive sheet, and the adhesive sheet moves with the adhesive tape to the position of the glue peeling plate after passing the glue feeding rollers, and moves to the beginning position of the area to be glued under the guidance of the glue peeling plate.

[0013] Furthermore, the tape includes a backing paper and a plurality of adhesive sheets spaced apart along the length of the backing paper; the adhesive feeding assembly further includes a backing paper winding feeder and a plurality of winding rollers disposed between the peeling plate and the backing paper winding feeder; the driving unit is used to drive the backing paper winding feeder to rotate so that the tape moves to the peeling plate after passing the adhesive feeding rollers, and drives the backing paper to move to the backing paper winding feeder for winding via the winding rollers.

[0014] Furthermore, the rolling mechanism includes a vertical drive unit, a mounting base connected to the output shaft of the vertical drive unit, and a rolling wheel rotatably disposed at the lower end of the mounting base.

[0015] Compared with the prior art, the workpiece adhesive applicator of the present invention has the following advantages: (1) The moving table can form an loading / unloading position and an adhesive applicator position, so that loading / unloading is unobstructed and convenient; (2) The adhesive feeding mechanism can send the first end of the adhesive sheet to the first end of the area to be adhesiveped, the rolling mechanism can press the first end of the adhesive sheet to the first end of the area to be adhesiveped, and the moving mechanism can drive the rolling mechanism to roll the adhesive sheet from the first end to the last end, which can roll every part of the adhesive sheet, so that the adhesive sheet is more tightly attached to the area to be adhesiveped, and prevent problems such as air bubbles and poor adhesion caused by some parts not being rolled; (3) The moving mechanism drives the adhesive feeding mechanism to move in the same direction while moving the rolling mechanism, and cooperates with the inclined peeling plate of the rolling mechanism and the adhesive feeding mechanism to peel off the adhesive sheet while applying adhesive, thereby improving the accuracy of the adhesive application position, improving the adhesive application efficiency, and improving the adhesive application effect; solving the problem that the adhesive sheet is easy to adhere to other objects due to the traditional process of peeling off the adhesive sheet first and then applying adhesive. (4) The glue feeding assembly is connected to the control module through the set detection unit. When the first end of the film protrudes to a predetermined distance from the lower inclined output end of the inclined peeling plate, it is regarded as the arrival signal of the first end position. It can accurately control the start and stop of film conveying and ensure that the first end of the film is effectively pressed to the first end position of the adhesive area during the pressing process of the rolling mechanism; (5) The release paper of the film is designed with a tear-off part. Colored patches are attached to the tear-off part. The detection unit is designed as a color mark sensor for sensing the colored patch. At the same time, the setting position of the detection unit is designed so that when the color mark sensor senses the signal, it is regarded as the film is in place. This achieves multiple benefits, realizes the position sensing function, and makes the tear-off part convenient for subsequent removal of the release paper; (6) The rolling roller of the rolling mechanism has a certain floating elasticity. The floating elasticity provides the reaction force for the rolling roller to move downward, so that when the rolling roller presses down on the film, the spiral spring is in a certain position.

[0016] The compressed state effectively allows the roller to press the adhesive sheet firmly onto the area to be bonded, preventing air bubbles from forming during application. In summary, the workpiece adhesive application device of this invention employs a roller-type moving adhesive application method, applying and peeling off adhesive simultaneously.

[0017] This method improves the accuracy of film placement, solves the problem of loose adhesive and air bubbles, increases adhesive application efficiency, and improves the yield of good adhesive products. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0040] Please see Figure 1 The workpiece adhesive applicator of the present invention includes a fixing fixture 100 for fixing workpiece A and an adhesive applicator module B for attaching adhesive film 442 to the adhesive application area of ​​workpiece A. The fixing fixture 100 is slidably mounted on a moving stage 200, allowing it to reciprocate along the length direction (hereinafter defined as the X-axis direction) of the moving stage 200. On a horizontal projection plane, a portion of the moving stage 200 that is misaligned with the adhesive applicator module B, for example, one end, is defined as an loading / unloading position, and a portion of the moving stage 200 that overlaps with the adhesive applicator module B is defined as an adhesive application station. This limitation allows the fixing fixture 100 to complete the loading / unloading of workpiece A at the loading / unloading position and the adhesive application process at the adhesive application station. The loading / unloading position is not obstructed by the adhesive applicator module B in any direction, providing a wider loading / unloading space and facilitating loading / unloading. In summary, the moving stage 200 is not considered an essential component, and in some embodiments, the fixing fixture 100 may also be fixedly placed at a certain position or on a platform.

[0041] Please see Figure 1 , Figure 2 and Figure 3In the illustrated embodiment, the moving stage 200 can be defined as a linear module 210, which is mounted on a frame 220 along the X-axis direction. The fixing fixture 100 is mounted on the slider of the linear module 210. The fixing fixture 100 includes a fixture platform 110 connected to the slider and positioning blocks 120 and / or positioning posts 130 mounted on the fixture platform 110 for positioning the workpiece A in the horizontal direction. The workpiece A can be defined as a plate-shaped workpiece, comprising an elongated plate A11 and two square plates A12 formed on one side of the width direction (hereinafter defined as the Y-axis direction) of the elongated plate A11. The two square plates A12 are spaced apart from each other on the same side of the elongated plate A11 along the X-axis direction, and each square plate A12 has an adhesive-to-gluing area formed on its upper surface. Therefore, workpiece A has two areas to be glued. One area can be defined as the first area A121 on the left side of the figure, and the other area can be defined as the second area A122 on the right side of the figure. Each time the adhesive application module B applies adhesive, it needs to attach two adhesive sheets 442 one-to-one to the two areas to be glued. Correspondingly, the two areas to be glued on workpiece A need to be moved sequentially to the adhesive application station. Therefore, the fixing fixture 100 needs to be moved twice. That is, when moving the fixing fixture 100 to the adhesive application station, the fixing fixture 100 can be moved first to place the first area A121 on the left side of the figure at the adhesive application station to complete the adhesive application process, and then the fixing fixture 100 can be moved a second time to place the second area A122 on the right side of the figure at the second adhesive application station to complete the adhesive application process. It should be understood that the number and location of the areas to be glued can be determined according to the glue application requirements of workpiece A in different embodiments. The two areas to be glued mentioned above are only limited as embodiments shown here and are not intended to limit the protection range of the workpiece glue application device of the present invention.

[0042] Please see Figure 1 , Figure 4 and Figure 5The adhesive application module B includes a mounting mechanism disposed on one side of the moving platform 200 along the Y-axis, a moving mechanism 300 disposed on the mounting mechanism, an adhesive feeding mechanism 400 disposed on the moving mechanism 300 facing the moving platform 200, a rolling mechanism 500 disposed on the moving mechanism 300 facing the moving platform 200, and a lifting mechanism 610 for lifting the mounting mechanism to provide the fixed fixture 100 with movement space from the loading / unloading station to the adhesive application station. The position directly below the initial position of the rolling mechanism 500 can be defined as the adhesive application station. For example, the position on the moving platform 200 directly below the rolling mechanism 500 is defined as the adhesive application station. When the area to be adhesiveped is located directly below the rolling mechanism 500, the fixed fixture 100 is considered to have moved to the adhesive application station. The glue feeding mechanism 400 is used to feed the adhesive sheet 442 to the adhesive-depositing area of ​​the workpiece A on the fixing fixture 100 at the adhesive application station. The rolling mechanism 500 is used to roll the adhesive sheet 442 onto the adhesive-depositing area. The moving mechanism 300 can be configured to move the glue feeding mechanism 400 and the rolling mechanism 500 along the X-axis. Specifically, when the rolling mechanism 500 presses the adhesive sheet 442 downward at the beginning position, it drives the rolling mechanism 500 to move towards the end position so that the rolling mechanism 500 rolls the adhesive sheet 442 onto the adhesive-depositing area from the beginning to the end. The moving mechanism 300 can also be configured to drive the glue feeding mechanism 400 to move towards the end position of the adhesive-depositing area so that the adhesive sheet 442 is peeled off from the glue feeding mechanism 400.

[0043] The design of the above-mentioned installation mechanism facilitates the integrated installation of the feeding mechanism and the rolling mechanism 500, making the adhesive application module B of the workpiece adhesive application device of the present invention more integrated, unified, and compact in layout. It also facilitates the attachment of the lifting mechanism 610, allowing the lifting mechanism 610 to lift the adhesive feeding mechanism 400 and the rolling mechanism 500 together, preventing the adhesive feeding mechanism 400 and the rolling mechanism 500 from obstructing the movement of the fixing fixture 100. The above-mentioned moving mechanism 300 drives the adhesive feeding mechanism 400 and the rolling mechanism 500 to move simultaneously in the same direction. When the rolling mechanism 500 presses the adhesive sheet 442 at the first end position, it causes the adhesive feeding mechanism 400 to move towards the tail end to achieve the adhesive peeling function, while simultaneously driving the rolling mechanism 500 to move towards the tail end to achieve the rolling adhesive application function from head to tail. It should be understood that the moving mechanism 300 is not considered an essential component. For example, in some embodiments, during roll-applied adhesive, the rolling mechanism 500 can remain stationary while the fixing fixture 100 moves relative to the rolling mechanism 500 to achieve full roll-applied adhesive. In other embodiments, the moving mechanism 300 can be configured to drive only the rolling mechanism 500 to move along the X-axis. After the adhesive feeding mechanism 400 feeds the adhesive sheet 442 to the area to be bonded in any way, the moving mechanism 300 rolls the adhesive sheet 442 along the X-axis after the rolling mechanism 500 presses the first end of the adhesive sheet 442, moving from the first end to the last end position so that the entire adhesive sheet 442 is firmly pressed into the area to be bonded. In yet another embodiment, the moving mechanism 300 can also be configured to correspond one-to-one with the adhesive feeding mechanism 400 and the rolling mechanism 500. The purpose of the lifting mechanism 610 is to provide the fixed fixture 100 with a moving space from the loading / unloading station to the adhesive application station, preventing the rolling mechanism 500 from obstructing the fixed fixture 100, thus providing a wider loading / unloading space for workpiece A and facilitating loading and unloading. In summary, the lifting mechanism 610 is not considered an essential component. Furthermore, it should be noted that the aforementioned "first end" can be defined as one end along the X-axis direction, and the aforementioned "tail end" can be defined as the other end along the X-axis direction. Alternatively, the "first end" refers to the end where the rolling mechanism 500 first contacts and presses the adhesive sheet 442, and the "tail end" refers to the other end that is rolled along the X-axis direction to the area to be adhesiveped.

[0044] The mounting mechanism can be defined as a mounting plate 620 standing sideways on the movable platform 200 along the Y-axis direction. The mounting plate 620 has strip-shaped perforations distributed along the X-axis direction, which penetrate the mounting plate 620 along the Y-axis direction. The lifting mechanism 610 can be defined as a lifting cylinder connected to the mounting plate 620 to drive the mounting plate 620 to rise and fall in a vertical direction (hereinafter referred to as the Z-axis direction), or a vertically arranged linear module 210, etc. The lifting height of the lifting mechanism 610, and the lifting and lowering of the mounting plate 620, can be controlled by any existing technical means, such as preset lifting / lowering strokes, limit switches, etc., which will not be elaborated here.

[0045] In the embodiment shown, the moving mechanism 300 includes a linear module 310 disposed on a side (hereinafter referred to as the back side) of the mounting plate 620 away from the moving stage 200 along the Y-axis direction, a guide rail module 320 disposed parallel to the linear module 310, and a moving base connected to the output shaft of the linear module 310 and the slider of the guide rail module 320. The linear module 310 is disposed on the back of the mounting plate 620 along the X-axis direction, directly opposite the strip-shaped perforation. The linear module 310 may include, for example, a lead screw 311 rotatably mounted on the back of the mounting plate 620 directly opposite the strip-shaped perforation, a lead screw nut 312 screwed onto the lead screw 311, a mounting block 313 connected to the lead screw nut 312, and a motor 314 disposed on the back of the mounting plate 620 and axially connected to one end of the lead screw 311. The mounting block 313 may pass through or through the strip-shaped perforation along the Y-axis direction and be connected to the movable base. The guide rail module 320 can be defined as a first guide rail 321 and a second guide rail 322 disposed along the X-axis on one side (hereinafter referred to as the front) of the mounting plate 620 facing the moving stage 200. The first guide rail 321 is disposed above the strip-shaped perforation in a manner parallel to the strip-shaped perforation, and the second guide rail 322 is disposed below the strip-shaped perforation in a manner parallel to the first guide rail 321. A slider (not shown) is slidably disposed on both the first guide rail 321 and the second guide rail 322. The sliders of the first guide rail 321 and the second guide rail 322 are connected to the back side of the moving base. The moving base can be defined as a moving base plate 330 with a plate-like structure. The back side of the moving base plate 330 is connected to the slider, and the front side of the moving base plate 330 is used for mounting the glue feeding mechanism 400 and the rolling mechanism 500. The rolling mechanism 500 and the glue feeding mechanism 400 are distributed along the X-axis on the front side of the moving base plate 330.

[0046] The glue feeding mechanism 400 includes a peeling plate disposed on the movable base, a glue feeding assembly 420 for moving the film 442 through the peeling plate to the beginning position of the area to be glued, and a detection unit 430 disposed on the movable base for detecting whether the beginning position of the film 442 has been delivered to the beginning position by the glue feeding assembly 420. The detection unit 430 is electrically connected to a control unit (not shown). When the glue feeding assembly 420 delivers the film 442 to the beginning position, the detection unit 430 detects a film 442 arrival signal, and the control unit controls the glue feeding assembly 420 to stop feeding glue based on the film 442 arrival signal detected by the detection unit 430.

[0047] Please see Figure 6 The peeling plate is disposed on one side of the movable base plate 330 facing the movable stage 200. One end of the peeling plate near the glue feeding assembly 420 is defined as an input end, and the other end near the rolling mechanism 500 is defined as an output end. The peeling plate can be defined as an inclined peeling plate 410. The input end is defined as an upper inclined input end 411 of the inclined peeling plate 410, and the output end is defined as a lower inclined output end 412 of the inclined peeling plate 410. The thickness of the lower inclined output end 412 gradually decreases in the direction away from the upper inclined input end 411. The inclined peeling plate 410 forms a first inclined surface 413 facing the first surface (lower surface in the figure) of the workpiece A along the Z-axis direction, and forms a second inclined surface 414 facing the second surface (upper surface in the figure) of the workpiece A away from the workpiece A along the Z-axis direction. The first inclined surface 413 is divided into two segments along the X-axis. One segment along the X-axis near the glue feeding assembly 420 is defined as a parallel surface segment 413a parallel to the second inclined surface 414. The other segment along the X-axis near the rolling mechanism 500 (i.e., away from the glue feeding assembly 420) is defined as a gradually inclined surface segment 413b that slopes towards the second inclined surface 414. One end of the gradually inclined surface segment 413b is connected to the parallel surface segment 413a, and the other end slopes towards the second inclined surface 414 and away from the glue feeding assembly 420, so that the end of the gradually inclined surface segment 413b away from the parallel surface segment 413a is connected to the second inclined surface 414. This connection forms a small sharp angle 415, and the angle α between the gradually inclined surface segment 413b and the parallel surface segment 413a is an obtuse angle.

[0048] In the illustrated embodiment, a mounting shaft 331 is provided on one side (front) of the movable substrate 330 facing the movable stage 200. One end of the mounting shaft 331 is connected to the portion of the front of the movable substrate 330 near the glue feeding assembly 420, and the other end extends along the Y-axis toward the movable stage 200. A rotating plate 332 is rotatably disposed on one end of the mounting shaft 331 near the movable substrate 330. The two side surfaces of the rotating plate 332 along the Y-axis are parallel to the movable substrate 330. A first oblong hole 333 is provided on one end of the rotating plate 332 near the glue feeding assembly 420. The first oblong hole 333 is located below the mounting shaft 331. A second oblong hole 334 is provided on one end of the rotating plate 332 near the rolling mechanism 500. The height of the second oblong hole 334 is adapted to that of the first oblong hole 333. The first oblong hole 333 and the second oblong hole 334 are both distributed on the rotating plate 332 along the Z-axis, and both the first oblong hole 333 and the second oblong hole 334 penetrate the rotating plate 332 along the Y-axis. The movable substrate 330 has a first fixing hole (not shown in the figure) at the position corresponding to the first waist-shaped hole 333, and a second fixing hole (not shown in the figure) at the position corresponding to the second waist-shaped hole 334. Both the first fixing hole and the second fixing hole can be multiple. The multiple first fixing holes and the multiple second fixing holes are arranged on the rotation trajectory of the first waist-shaped hole 333 and the second waist-shaped hole 334 around the mounting shaft 331.

[0049] The aforementioned inclined peeling plate 410 and detection unit 430 are both mounted on the rotating plate 332 so that the tilt angle can be adjusted as the rotating plate 332 rotates. Specifically, a pivot lug 416 is provided on the side of the inclined peeling plate 410 away from the rotating plate 332 along the Y-axis. A pivot hole 417 is formed on the pivot lug 416. The pivot hole 417 is rotatably engaged with the end of the mounting shaft 331 away from the moving base plate 330. The side of the inclined peeling plate 410 facing the rotating plate 332 is fixedly connected to the rotating plate 332. When adjusting the tilt angle of the inclined peeling plate 410, the rotating plate 332 is first rotated around the mounting shaft 331 to the corresponding angle. The inclined peeling plate 410 rotates together with the rotating plate 332. After rotating to the corresponding angle, multiple fixing bolts are passed through the first waist-shaped hole 333 and the second waist-shaped hole 334 and fixed in the first fixing hole and the second fixing hole, thereby fixing the inclined peeling plate 410 in the tilted state.

[0050] Please see Figure 7 and Figure 8In the illustrated embodiment, the film 442 is embodied as tape 440. The tape 440 includes a backing paper 441 and a plurality of films 442 spaced apart along the length of the backing paper 441. Each of the plurality of films 442 includes a film body 4421 and a detection portion 4422 disposed at one end of the film body 4421. The film body 4421 includes a double-sided film 4421a adhered to the backing paper 441 and an anti-adhesion sheet 4421b covering the surface of the double-sided film 4421a facing away from the backing paper 441. The anti-adhesion sheet 4421b can be any material layer that prevents objects from directly contacting and adhering to the double-sided film 4421a while maintaining the adhesiveness of the double-sided film 4421a after being peeled off, such as release paper. The detected part 4422 can be defined as a tearable part 4422a extending outward from one end of the anti-stick sheet 4421b. The tearable part 4422a is elongated and has a colored patch 4422b, such as a blue PET strip, on the surface away from the backing paper 441. The surface of the blue PET strip is covered with an adhesive layer that facilitates adhesion to the hand when tearing. Therefore, the colored patch 4422b can also be defined as a colored film 442. Corresponding to the two areas to be glued in the illustrated embodiment, among the plurality of films 442 adhered to the backing paper 441, each pair of adjacent films 442 forms a film pair corresponding one-to-one with the two areas to be glued on a workpiece. According to the adhesive application requirements, the detection portions 4422 of the two films 442 in each film pair are arranged adjacently. That is, in each film pair, the detection portion 4422 (tearable portion 4422a) of one film 442 is located on an edge of that film 442 facing the adjacent film 442, and the tearable portion 4422a of the other film 442 is located on an edge of that film 442 facing the first film 442. According to requirements, the two tearable portions 4422a in each film pair are spaced apart along the Y-axis direction. It should be understood that in different adhesive application requirements, the two detection portions 4422 of each film pair may also be arranged back-to-back.

[0051] Corresponding to the colored patch 4422b, the detection unit 430 is defined as a color mark sensor. The position of the color mark sensor on the rotating plate 332 is defined such that when the leading end of the film 442 reaches the leading end position, the color mark sensor can detect the colored patch 4422b. That is, after the color mark position sensor is installed on the rotating plate 332 according to the set position, during the detection process, when the color mark sensor detects the colored patch 4422b, the leading end of the film 442 is exactly delivered to the leading end position outside the downward inclined output end 412 of the inclined peeling plate 410. This leading end position can be specifically defined as a position that coincides with the leading end position of the area to be glued on the horizontal projection plane, for example, directly attached to the leading end of the area to be glued, or for example, located directly above the leading end of the area to be glued. In the illustrated embodiment, the lifting mechanism 610 needs to first lift the mounting mechanism to allow the fixing fixture 100 to move to the adhesive application station. Therefore, the "first end position" here refers to the position directly above the first end of the area to be adhesiveped and directly below the rolling mechanism 500. As an example, when the first end of the film 442 protrudes from the downward inclined output end 412 of the inclined peeling plate 410 by a distance of approximately 10-20 mm, such as 15 mm, it is considered that the protruding first end of the film 442 has reached the "first end position". The setting position of the color mark sensor is specifically defined as the color mark sensor detecting the colored patch 4422b precisely when the first end of the film 442 protrudes by the set 15 mm.

[0052] Please continue reading. Figure 5 The glue feeding assembly 420 includes a glue dispensing feeder 421 for carrying the adhesive tape 440, a plurality of glue feeding rollers 422 disposed between the glue dispensing feeder 421 and the peeling plate, a backing paper winding feeder 423, a plurality of winding rollers 424 disposed between the peeling plate and the backing paper winding feeder 423, and a drive unit 425 for driving the glue feeding rollers 422 and the winding rollers 424. The film 442 moves with the adhesive tape 440 after passing the glue feeding rollers 422 to the position of the peeling plate, and moves to the beginning position of the area to be glued under the guidance of the peeling plate; after the film 442 peels off the adhesive tape 440, the remaining backing paper 441 is folded back by the sharp corner 415 and the second inclined surface 414 of the inclined peeling plate 410 and then moved by the winding rollers 424 to the backing paper winding feeder 423 for winding.

[0053] The glue dispensing feeder 421 is disposed on the mounting plate 620 at one end away from the rolling mechanism 500, and is located near the upper end of the mounting plate 620. The bottom paper winding feeder 423 is disposed on the mounting plate 620 at one end away from the rolling mechanism 500, and is located near the lower end of the mounting plate 620. Of the plurality of glue feeding rollers 422, a portion, such as two glue feeding rollers 422, is rotatably disposed on the mounting plate 620, and the two glue feeding rollers 422 are spaced apart between the glue dispensing feeder 421 and the inclined peeling plate 410 according to a predetermined glue feeding route. Another portion, such as one glue feeding roller 422, is rotatably disposed on the movable substrate 330 so as to move with the movable substrate 330, and the glue feeding roller 422 on the movable substrate 330 is located near the mounting shaft 331. Of the plurality of take-up rollers 424, a portion, for example, three take-up rollers 424 are disposed on the mounting plate 620. The three take-up rollers 424 are spaced apart between the backing paper take-up feeder 423 and the inclined peeling plate 410 according to a predetermined take-up route. Another portion, for example, two take-up rollers 424 are disposed on the movable base plate 330 near the backing paper take-up feeder 423. Among the three take-up rollers 424, one take-up roller 424a near the inclined peeling plate 410 is located below the movable base plate 330 and is located between the two ends of the movable base plate 330 along the X-axis. Of the two take-up rollers 424, in the X-axis direction, the horizontal distance between one take-up roller 424b and the end of the movable substrate 330 near the take-up feeder 423 is greater than the horizontal distance between the other take-up roller 424c and the end of the movable substrate 330 near the take-up feeder 423. That is, the other take-up roller 424c is closer to the end of the movable substrate 330 near the take-up feeder 423 than the first take-up roller 424b. In the Z-axis direction, the vertical distance between one take-up roller 424b and take-up roller 424a is greater than the vertical distance between the other take-up roller 424c and take-up roller 424a. In summary, the take-up rollers 424a, one take-up roller 424b, and the other take-up roller 424c are arranged in a triangle, and this triangular shape changes as the movable substrate 300 moves. Additionally, when the movable substrate 300 drives the inclined peeling plate 410 to move and peel adhesive along the X-axis direction of the adhesive feeding assembly 420 (left side in the figure) (i.e., when the inclined peeling plate 410 moves and peels adhesive from beginning to end), the other take-up roller 424c extends beyond the take-up roller 424a in the corresponding direction. The distance of the extension should be set to ensure that the film 442 can be completely peeled off from the backing paper 441.

[0054] The tape 440 is led out by the glue feeder 421, passes sequentially through each glue feeding roller 422 on the mounting plate 620 and the glue feeding roller 422 on the moving base plate 330, passes through the gap between the mounting shaft 331 and the inclined peeling plate 410, and finally passes through the second inclined surface 414 of the inclined peeling plate 410 and is delivered to the outside of the sharp corner 415 so as to be located directly below the rolling mechanism 500 (i.e. delivered to the first end position). After the film 442 is peeled off and applied to the area to be glued, the backing paper 441 corresponding to the peeled film 442 is folded back from the sharp corner 415 of the inclined output end 412 of the inclined peeling plate 410, and is wound into the backing paper winding feeder 423 after passing through the first inclined surface 413 of the inclined peeling plate 410, one winding roller 424b, another winding roller 424c, and the winding roller 424 on the mounting plate 620.

[0055] The drive unit 425 can be defined as a drive motor. The drive motor is connected to the bottom paper winding feeder 423 through a transmission chain, transmission gears and other transmission methods, so as to drive the bottom paper winding feeder 423 to rotate and pull the bottom paper 441 forward, thereby driving the tape 440 to move from the glue dispensing feeder 421 to the inclined peeling plate 410.

[0056] In the illustrated embodiment, a clamping mechanism for clamping the adhesive tape 440 during application is further provided at a position between the adhesive feeding roller 422 on the mounting plate 620 located on the movable substrate 330 and an adjacent adhesive feeding roller 422 on the mounting plate 620. The clamping mechanism includes a support platform 451 horizontally arranged on the front side of the mounting plate 620 along the Y-axis direction and a clamping unit arranged on the mounting plate 620 along the Z-axis direction and located directly above the support platform 451. The clamping unit may be defined as including a clamping cylinder 452 and a pressure block 453 arranged on the output shaft of the clamping cylinder 452. The clamping cylinder 452 can be electrically connected to the control unit through an electronic control component such as a solenoid valve. When it is necessary to peel off the film 442 for adhesive application, the pressing cylinder 452, under the control of the control unit, presses down on the adhesive tape 440 on the support platform 451 so that the adhesive tape 440 stops moving forward, ensuring that the film 442 is completely peeled off from the backing paper 441.

[0057] Please see Figure 1 and Figure 9The rolling mechanism 500 is used to move downward to press the adhesive sheet 442 at the first end position when the adhesive feeding assembly 420 stops feeding adhesive. Specifically, it can be defined that after the pressing cylinder 452 presses the adhesive tape 440 onto the support platform 451, the rolling mechanism 500 moves downward to press the adhesive sheet 442 at the first end position. The rolling mechanism 500 includes a base 510 disposed on the front side of the movable substrate 330 along the Y-axis direction, a vertical drive unit 520 disposed on the base 510 in the vertical direction, a mounting base 530 connected to the output shaft of the vertical drive unit 520, and a rolling wheel 540 rotatably disposed at the lower end of the mounting base 530. The vertical drive unit 520 can be defined as a cylinder, hydraulic cylinder, push rod motor, etc. A first slide rail assembly is provided on the first surface of the base 510 facing away from the inclined peeling plate 410 along the X-axis direction. The first slide rail assembly includes two first slide rails 511 spaced apart along the Y-axis direction. Each of the two first slide rails 511 is distributed on the first surface of the base 510 along the Z-axis direction, and each first slide rail 511 is slidably equipped with a first slider 512. The second surface of the mounting base 530, which is directly opposite the first surface of the base 510 along the X-axis direction, is connected to the first slider 512 of the first slide rail assembly. The side of the mounting base 530 near the vertical drive unit 520 along the Z-axis direction is connected to the output shaft of the vertical drive unit 520.

[0058] The mounting base 530 includes a connecting portion 531 connected to the output shaft of the vertical drive unit 520 and slidably engaged with the first slide rail assembly, a floating mounting portion 532 disposed on the connecting portion 531, and a rolling roller mounting portion 533 disposed on the floating mounting portion 532. The rolling roller 540 is rotatably mounted on the lower end of the rolling roller mounting portion 533. A second surface on the connecting portion 531, which is directly opposite to the first surface of the base 510, is connected to the first slider 512. The side of the connecting portion 531 closest to the vertical drive unit 520 along the Z-axis direction is connected to the vertical drive unit 520. The floating mounting portion 532 includes a mounting plate 5321 connected to a first surface on the connecting portion 531 that is opposite to the second surface along the X-axis direction, and a horizontal flange 5322 extending from the upper end of the mounting plate 5321 along the X-axis direction away from the connecting portion 531. A second slide rail assembly 550, with the same or similar structure or function as the first slide rail assembly, is provided on the first surface of the mounting plate 5321 opposite to the connecting portion 531 along the X-axis direction. The second slide rail assembly 550 includes two second slide rails and two second sliders respectively disposed on the two second slide rails. At least one, for example two, floating mounting posts 561 are also provided on the first surface of the mounting plate 5321 at a position between the two second slide rails. Each floating mounting post 561 is distributed along the Z-axis direction, and the upper end of each floating mounting post 561 is connected to the horizontal flange 5322, and a stop block (not shown in the figure) is provided around the lower end. A floating block 563 is movably fitted onto the floating mounting column 561. The floating block 563 is blocked by the stop block and does not continue to move downward. A helical spring 562 is looped around the section of the floating mounting column 561 between the floating block 563 and the horizontal protrusion 5322. The upper end of the helical spring 562 abuts against the horizontal protrusion 5322, and the lower end is connected to the floating block 563. The roller mounting part 533 has a connecting plate 5331 connected to the floating block 563 and two adapter ears 5332 disposed below the connecting plate 5331. The two adapter ears 5332 are spaced apart along the Y-axis at the lower end of the connecting plate 5331. The two ends of the roller 540 are rotatably disposed at the adapter ears 5332. The roller 540 can be located at the beginning of the area to be glued and directly above the beginning of the adhesive sheet 442 protruding from the downward tilting output end 412.

[0059] The principle of adhesive application in this embodiment of the invention is as follows: (1) Loading: The main control module (e.g., host computer, PLC controller, and the control unit mentioned above) of the workpiece adhesive application device controls the linear module 210 to move the fixed fixture 100 to the loading / unloading position, and places the workpiece A on the fixed fixture 100; (2) The control module controls the lifting mechanism 610 to lift the mounting plate 620 and the adhesive feeding mechanism 400 and the rolling mechanism 500 on it, so that the fixed fixture 100 moves to the adhesive application position. When the fixed fixture 100 moves to the adhesive application position, the The control module controls the lifting mechanism 610 to reset the mounting plate 620 and its glue feeding mechanism 400 and rolling mechanism 500. In the illustrated embodiment, since there are two glue-to-be-adhesive areas, which are spaced apart along the X-axis, there are two glue-applying stations: First, the fixing fixture 100 is moved to the first glue-applying station, so that the first end of the first glue-to-be-adhesive area A121 on the left side of the figure is directly below the rolling roller 540; after the glue is applied to the first glue-to-be-adhesive area A121 on the left side, the fixing fixture 100 continues to move to the left. (2) Move so that the first end of the second adhesive-bearing area A122 on the right side of the figure is directly below the roller 540; (3) Glue feeding of the first adhesive-bearing area A121 on the left: The control module lifts the clamping cylinder 452 upward, and the control module controls the winding flyer 423 to rotate and wind in the predetermined rotation direction. While the bottom paper 441 is being retracted, the tape 440 is driven forward to the inclined peeling plate 410. When the first end of the tape 440 protrudes to the front of the inclined output end 412 of the inclined peeling plate 410 by a set value, such as 15mm as mentioned above, the control module controls the tape to be fed to the inclined peeling plate 410. The glue feeding assembly 420 stops feeding glue (even if the drive unit 425 stops driving); (4) Pressing glue into the first glue-to-adhesion area A121 on the left: First, the control module controls the pressing cylinder 452 to move downward to press the tape 440 at the position of the support platform 451 to prevent the tape 440 from moving. Second, the control module causes the vertical drive unit 520 of the rolling mechanism 500 to drive the rolling wheel 540 to move downward. The rolling wheel 540 presses the tape 440, which protrudes 15mm, vertically down onto the first end of the first glue-to-adhesion area A121 on the left directly below.(5) Peeling and rolling adhesive onto the film 442 corresponding to the first adhesive-bearing area A121 on the left: The control module controls the moving mechanism 300 to work, causing the moving mechanism 300 to move the inclined peeling plate 410 towards the tail end of the first adhesive-bearing area on the left along the X-axis. During the movement, the tape 440 is pressed by the pressing mechanism and the beginning end of the film 442 is pressed by the rolling roller 540. Also, the moving base plate 330 drives one of the take-up rollers 424b and the other take-up roller 424c to move synchronously and in the same direction, which increases the folding stroke of the backing paper 441. Thus, when the tape 440 is pressed and stationary, the inclined peeling plate 410 is moved to drive the backing paper 441 away from the film 442, causing the film 442 to be passively peeled off from the backing paper 441. While peeling off the adhesive, since the rolling mechanism 500 is also installed on the moving mechanism 300, the rolling roller 540 simultaneously rolls the adhesive sheet 442 onto the area to be glued from the front end to the rear end, completing the adhesive application process for the first area to be glued A121 on the left; (6) The control module returns the moving mechanism 300 to the initial position, thereby returning the rolling mechanism 500 to the initial position; (7) The fixing fixture 100 is moved to the second adhesive application station according to the method in step (2), so that the front end of the second area to be glued A122 on the right side in the figure is directly below the rolling mechanism 500 in the initial position; the adhesive sheet 442 is applied to the second area to be glued A122 on the right side according to the same or similar method in steps (3) to (6), thus completing the adhesive application process for the two areas to be glued of a workpiece A.

[0060] The workpiece adhesive applicator of the present invention has the following beneficial effects: (1) The moving table can form an loading / unloading position and an adhesive applicator position, so that loading / unloading is unobstructed and convenient; (2) The adhesive feeding mechanism can deliver the first end of the adhesive sheet to the first end of the area to be adhesiveped, the rolling mechanism can press the first end of the adhesive sheet tightly against the first end of the area to be adhesiveped, and the moving mechanism can drive the rolling mechanism to roll the adhesive sheet from the first end to the last end, which can roll every part of the adhesive sheet, so that the adhesive sheet is more tightly attached to the area to be adhesiveped, and prevents the adhesive sheet from being damaged due to improper handling. Problems such as air bubbles and incomplete adhesion caused by some not being rolled; (3) The moving mechanism moves the rolling mechanism while driving the glue feeding mechanism to move in the same direction. It works in conjunction with the inclined peeling plate of the rolling mechanism and the glue feeding mechanism to peel off the film while applying the glue, thereby improving the accuracy of the glue application position, improving the glue application efficiency, and improving the glue application effect; It solves the problems caused by the traditional process of peeling off the film first and then applying the glue, such as the film easily adhering to other objects, misaligned film adhesion, and air bubbles; (4) Glue feeding group The component is connected to the control module through the set detection unit. When the first end of the film protrudes to a predetermined distance from the lower inclined output end of the inclined peeling plate, it is regarded as the arrival signal of the first end position. It can accurately control the start and stop of film conveying and ensure that the first end of the film is effectively pressed to the first end position of the adhesive area during the pressing process of the rolling mechanism; (5) A tear-off part is designed at the release paper of the film. A colored patch is attached to the tear-off part. The detection unit is designed as a color mark sensor for sensing the colored patch. At the same time, the setting position of the detection unit is designed so that when the color mark sensor senses the signal, it is regarded as the film is in place. This achieves multiple benefits, realizes the position sensing function, and makes the tear-off part convenient for subsequent removal of the release paper; (6) The rolling roller of the rolling mechanism has a certain floating elasticity. The floating elasticity provides a reaction force for the rolling roller to move downward. When the rolling roller presses down on the film, the spiral spring is compressed, which effectively makes the rolling roller press the film to the adhesive area and prevents the appearance of adhesive bubbles. In summary, the workpiece adhesive applicator of this invention adopts a roller-type moving adhesive applicator, which improves the accuracy of adhesive film placement by applying and peeling off adhesive simultaneously, solves the problem of loose adhesive and air bubbles, improves adhesive application efficiency, and increases the yield of adhesive-applied products.

[0061] The above embodiments merely illustrate preferred implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention should be determined by the appended claims.
